(Cl. 92-43) The principal objects ofthe invention are'directed to the provision of paper-making appara- 4tus wherein a cylinder mould is adjustable rela'- tive to the adjacentwall or Walls of the vat in` order to meet various conditions andrequirelo ments.

ld between the mould and In paper-making apparatus of the type to whichthe invention relates a cylinder mould rotates in a vat which isprovided with a wall or walls adjacent the mould, there being a spacewall for paper-making material, the bers of which are taken on by theforaminous surfacesof the mould.

In order to produce certain results insofar as possible the Wall orwalls have been of certain Wcontours and spaced certain distances fromthe cylinder mould. That is to say, when lt is desired to produce acertain kind of paper it has been customary to locate the `wall or wallsadjacent the cylinder mould and so form it in such a way as to provide acertain space between the mould and wall and to use paper-making ma-'terial of certain consistency and rotate the mould in a certain way.lin other words'gfor certain predetermined results the wall is of acertain W shape and a certaindistance from the cylinder mould, thecharacteristics of the paper-making material for the particular resultare more or less denlte,r and the speed of the cylinder is within acertain range. The space between the cylinder and wall is of courseconstant and therefore an important factor and the characteristicsof thepaper-making materiaLspeed of the cylinder, and other factors withinrelatively narrow limits.

l ere it is desired or necessary to produce the same kind of papercontinuously it is possible to produce reasonably good results but Yitis dicult and sometimes impossible to vary all of the factors to produceequally good results where it is desired to produce other kinds of paperbecause of the denite relationship of the cylinder and wall. To producea certain result with papermaking material of certain characteristicsthe cylinder and wall must have a certain relationship. Where it isdesired to product another result with the same or differentpaper-making materialthe cylinder and wall should have a differentrelationship. But si ce the relationshipA ls constant it is impossibleat times to use the "material desired. 'Altogether the type of paper'-nlust consequently be controlled ferent.

making material and speed of the cylinder are varied in order toaccommodate lthe constant relationship of the cylinder and Wall. A

According to this invention, instead of varying the numerous factors inorder to produce a certain result or a certain kind of paper or ofattempting. to mais` the various factors/accommodate themselves to thedefinite relationship of the cylinder mould and adjacent Wall, thereisprovided a wall or walls adjacent the cylinder lo which are of suchshape'as suce for general purposes and the cylinder 'ls adjustablerelative to the wall or'walls. To accomplish this the cylinder mould lsmovable back and forth and up and down relative to the vat and the wallor ld walls adjacent thereto so as to provide a varying space betweenthe cylinder mould and wall.

It is possible to set the cylinder mouldto provide either a small orrelatively greater space bev tween it and the adjacent wall and the saidspace no may be of greater width at its upper than at its lower side orit may have a constant width. Or the cylinder may be moved to providespaces between it and adjacent walls which are similar or are relativelylarger or smaller than one anas other.

Itbeing possible to vary the space between the Icylinder and wall orwalls, the varying of results within wide limits is facilitated. That isto say, with a certain result vto be obtained by the do use of a certain'paper-making material, a certain operating speed, etc. the mould may belocated with reference to the adacent wall or walls to provide such aspace as willoperate to the best advantage with the other factors togive a5 the desired result. For instance, to produce ya certain kind ofpaper with a paper-making material having certain characteristics thespace between the cylinder and wall may need to have a certain formwhile to produce another kind im,y

of paper with the same or another type of papermaking material the spacemay need to be dif- The adjustability of the cylinder relative to theadjacent wall or walls therefrom makes it possible'to produce thedesired results by the 4t use of paper-making material best suited forthose results. The paper-making apparatus is variable to accommodate thedesired results and conditions rather than conditions being varied tosuit the apparatus, all to the end that not only -50 is economy 'andefficiency in operation made possible but the resul/ts are withincontrolv and uniform papers are produced.

The invention may be practiced in various ways butl for purposes ofdisclosure the following deaccompanying drawing of the invention; and

Fig. 2 is an enlarged fragmentary sectional ele-I vational view takenthrough one end of the apy, lar wall 24, is provided lparatus shown inFig. 1.

Referring now to the drawing in detail the invention will beV fullydescribed.

. In Fig. 1 which is an end elevational view of the apparatus of theinvention there is shown a vat 2 in which is rotatable a cylinder mould4 of .usual form. As in apparatus of this type, the

cylinder maybe rotated by any suitable lfmeans.

At the forward and rear ends of the vat 2 there is an end plate or endwall member such as 6 which may be of cast iron or some other suitablematerial. Between the end plates 6 there is a bottom wall 8 and sidewalls III and the said end plates and walls are suitably securedtogether in vat-forming relation.

A vertical wall is indicated by the end, right-hand side and bottomwalls 6, 8 and III, what may be called an inlet chamber. Paper-makingmaterial may be delivered to this chamber in any desired manner so thatit flows up and overwall I2, across a horizontal wall I4, and up andover the upper end I6 of a wail I8 into a space 28 between cylinder 4and said wall I8. A'baiiie 22lmay be provided which is adjustable up anddown relative to walls I2 and I8 if desired. 'I'he wall I8 is curved asshown to more or less follow the curvature of the cylinder mould and acontinuation thereof, or another separate simiat the other side of thecylinder. As paper-making material is delivered into. the space in whichthe cylinderl rotates the fibers thereof are taken on by the cylindermould and water passing through the foraminous surface of the cylinderpasses into compartment 80 of the end plate making material passes upand over the upper end 28 of wall 24 and into chamber 32. Excess waterand paper-making material are conducted from the vat in the usual way.

By curving the walls I8 and 24 substantially as shown and by providingmeans for moving or adjusting the cylinder up and down and back andforth in the vat relative to said walls it is possible to provide arelationship of the cylinder and wall or a Aspace therebetween ofvvariable size and I'2 to provide with form. Means for moving oradjusting the cyl' Inder may be associated with each end plate 8 andsince the means at each end of the vat will I be substantially similar adescription of the means at one end of the vat will suffice. y

The end plate 8 at its upper side is cut away to provide an open-endedor U-shaped opening 48 and a supporting plate 42 has its side and loweredges formed to receive the plate 6 at its edges around said opening. Inthis way the plate 42 is slidable up and down and back and forthrelative to the end plate.

A shelf part or ledge 44 extends forwardly of the supporting plate 42and this may support a bearing or journal 44 for shaft 48 of thecylinder mould. For clearness, the bearing 44' is omitted in Fig.1.Aninner pl te 48 lies against the supporting plate 42 .and I'xverliesvan open-ended slot Il therein.`

' A'stumns box 54 provided on plate 48 receives `the shaft 48 and theremay be a gland 58 assoc' lated therewith for packing the shaft andallowing rotation thereof. As previously explained.

' 6 up and.- down as well there are upper and .These latter gears orplates while excess paper-` n4whereby said cylinder the supporting plate42 is adjustable on plate as back and forth and this may be accomplishedin various ways. y

According to one embodiment ofthe invention lower screws or threadedshafts 80 and 62. 'I'he upper shaft GII is rotatable in bearings 84associated with plate 6 and a threaded portion 86 thereof is in fthreaded er1- gagement with a nut 68 which is disposed between abutments10 associated with the plate 42. As member 60 is rotated the plate 42 ismoved back and forthin one direction or the other according to thedirection of rotation of said member 68.

The screw shaft 82 has threaded portions 62 which are preferably rightand left hand and these threadedly engage block members 12 that areguided on or in shelves 15 associated with and extending forwardly fromplate 6. By rotating menber 62 in one direction or the other the blocks12 are moved towards or away from one another. The blocks 12 havepivoted thereto as at 14 the lower ends of links or connectors 16 theupper ends of which links are pivoted at 18 to plate 42 whereby the saidplate 42 is moved up or down by the blocks 12 and screw shaft 82.

The screw shafts 60 and 62 may be rotated in any well known manner butin the form of the invention shown they carry gears 80 and 82 whichmesh-with gears 84 and 86 respectively. may be fixed to the forward endsof longitudinally extending shafts 88 and 90 which carry on their otherends other gears similar to those gears 84 and 86 for operating screwshafts associated with the end plate at the other or rear end of thevat. In this way as shafts 88 and 98 are rotated the shafts 68 and 62vassociated with both end plates are simultaneously rotated. y

Thus it will be seen, one shaft and associated gears are adapted to movethe plate up and down so as to move the cylinder up and down, while theother shaft and its associated gears are adapted to move the cylinderback and forth.

While I have described the invention in great of, it is not desired tobe limited thereto since man'y changes and modifications may be madetherein without departing from the spirit and scope of the invention.What it is desired to claim and secure by Letters Patent of the UnitedStates is:

Paper making apparatus comprising in combination, a vat having end wallsandspaced relatively flxed rigid longitudinal walls therebetweenextending downwardly and inwardly from their upper portions, a cylinderbetween said walls, supporting plates rotatably supporting the cylinderslidable on the end walls. means associated with the end walls andsupporting plates for moving said plates vertically relative to the endwalls and means for moving said plates horizontally relative to the endwalls, all adapted and arranged may be moved towards and 'away from andup and down relative to the longitudinal walls to vary the space betweensaid cylinder and walls at the sides and bottom of the cylinder, thefirst named means including blocks slidably guided on the'end walls formovements towards and away from oneanother, links connected at oppositeends to said blocks and to said supporting plates and rotatableactuating members held against axial movements having screw threadsformed thereon and engaged in corresponding screw threads formed in saidblocks.
